[Bug tree-optimization/43141] New: [4.5 Regression] Wrong debug information with IPA-SRA

[rguenth at gcc dot gnu dot org]

Split out from PR42336.

But here's a C testcase where we lose debug info about a parameter that was
optimized away: there are no formal parameters in the DWARF output for f.

int i;
static int f(int) __attribute ((noinline));
static int f(int x) { return i; }

int main()
{
  return f(42);
}
